  2. 2. Modification of Paper into Conductive Substrate for Electronic Functions : Deposition, Characterization and Demonstration

    Author : Elson Montibon; Magnus Lestelius; Lars Järnström; Jouko Peltonen; Karlstads universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic paper; electroconductive paper; flexible electronics; conducting polymer; ionic liquids; fiber network; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

    Abstract : The thesis investigates the modification of paper into an ion- and electron-conductive material, and as a renewable material for electronic device. The study stretches from investigating the interaction between the cellulosic materials and the conducting polymer to demonstrating the performance of the conductive paper by printing the electronic structure on the surface of the conductive paper.

  4. 4. Functional composite coatings containing conducting polymers

    Author : Shadi Jafarzadeh; Per Martin Claesson; Arjan Mol; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Conducting polymer; Polyaniline; Conductive network; Nanocomposite; Active corrosion protection; Interfacial energy; UV curing; Kemi; Chemistry;

    Abstract : Organic coatings are widely used to lower the corrosion rate of metallic structures. However, penetration of water, oxygen and corrosive ions through pores present in the coating results in corrosion initiation and propagation once these species reach the metal substrate. READ MORE

  5. 5. Lithium Ion Conductive Membranes Based on Co-continuous Polymer Blends

    Author : Anette Munch Elmér; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; Polymer technology; biopolymers; conductivity measurements; in-situ UV-polymerisation; solution casting; poly methyl methacrylate ; vinylidene fluoride copolymers; poly ethylene carbonate-co-ethylene oxide methacrylate; PEG methacrylate macromonomers; heterogeneous polymer blends; polymer electrolyte membranes; lithium salt containing gels;

    Abstract : There is a growing need for multifunctional polymeric materials for the development of several important energy conversion technologies. For example, the polymer electrolyte is a key component in lithium polymer batteries. The basic functions of this electrolyte are to efficiently conduct the lithium ions and physically separate the electrodes. READ MORE
